任何产品在生产过程中难免会出现一些质量问题，在铝板生产过程中，因为设备或者人员操作失误等原因容易出现质量问题，下面铝板生产厂家进行铝板使用期间出现三种“伤”原因分析。
Any product will inevitably have some quality problems in the production process. In the aluminum plate production process, quality problems are likely to occur due to equipment or personnel misoperation and other reasons. The aluminum plate manufacturer will analyze the causes of three kinds of "injuries" during the use of aluminum plates.
划伤：划伤、擦伤、碰伤是铝板表面呈现的断续或连续的.单条沟状伤痕。一般是尖锐物与箔材表面接触后相对滑动时产生的。产生的主要原因:轧辊、导辊表面有尖状缺陷，或粘有硬杂物;剪切、合卷、分切的机械导辊、导路有尖状缺陷或枯有杂物。
Scratches: Scratches, scratches and bruises are intermittent or continuous on the aluminum plate surface Single groove scar. It is generally caused by the relative sliding of sharp objects after contacting with the foil surface. The main causes: there are sharp defects on the surface of the roll and guide roll, or there are hard impurities; The mechanical guide roller and guide path for shearing, coiling and slitting have sharp defects or debris.

擦伤:由于物体间棱与面，或面与面接触后发生相对滑动或错动而在箱材表面造成的成束(或组)分布的伤痕。擦伤产生的主要原因:铝板在加工生产过程中，与导路、设备接触时，产生相对摩擦而造成擦伤;坯料松卷、松层或有燕窝状端面缺陷;轧制时张力使用不当，开卷时产生层间错动而产生擦伤。
Scratch: refers to the bundle (or group) of scars on the surface of box material caused by relative sliding or dislocation between edges and surfaces of objects or after the contact between surfaces. The main causes of scratches are as follows: during the processing and production of aluminum plate, when it contacts with the guide road and equipment, it will produce relative friction and cause scratches; The blank is loose, has loose layers or has bird's nest shaped end defects; Improper use of tension during rolling, interlaminar stagger during uncoiling, resulting in scratches.
碰伤:铝卷与其他物体相撞后，在箱卷表面或端面产生的伤痕。其表现为表面或端面有部分凹陷。碰伤的主要原因:各生产工序吊运或存放不当;运输及搬运过程中碰伤;铝箔卷在退火料架或包装台上由其他突出物磕碰而产生伤痕。
Bump: the scar on the surface or end face of the case coil after the aluminum coil collides with other objects. The surface or end face is partially concave. The main causes of bruise: improper hoisting or storage of each production process; Collision during transportation and handling; The aluminum foil roll is bumped by other protrusions on the annealing material rack or packaging table, resulting in scars.
